If I start both hosts up at the same time, they join just fine, but if I reboot one, I have to disable iptables on both hosts
Here's the IP tables I have going for now after trying some troubleshooting:
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.

Of caurse the source IPs are changed on the other node. Am I missing anything or does something look too restrictive? I appreciate the help
